Diodes - Zener - Single, is a component category for the 1EZ100D5E3/TR12 application field and its working principle. This product family of single Zener diodes offers an extensive selection of voltage ratings and power dissipation levels that can handle a wide variety of applications. While the voltage breakdown of Zener diodes is near that of regular rectifier diodes, the Zener diode is designed so that it can withstand large voltage breakdown levels and prevents its current from using the Voltage Breaks (VBR) as its current path. These characterizations make the 1EZ100D5E3/TR12 Single Zener Diode series very applicable for voltage regulating and other system-level applications.

This series of devices is comprised of small-signal, surface-mount signal diodes. Unlike normal rectifier diode, a Zener diode is designed to operate opposed to its normal bias. This allows a current to flow through it at a constant voltage level even if the input voltage to it vary with the current load of the system. This allows Zener diodes to offer voltage regulation to systems in which the input voltage varies due to its current load. In systems where the input voltage fluctuates due to load changes, the output of the system can remain at the same regulated voltage level.

Most Zener diodes rely on the Zener breakdown phenomenon to regulate the voltage output level. The Zener break process involves a threshold point where the device stops behaving as a traditional diode and turn into a voltage-dependent resistor. When the voltage breakdown of the devices exceed the Volt-ampere characteristics of the device, electrons rush through the active area and flow in the direction of the PN junction to form an avalanche current. As this avalanche current passes through the device, a build-up of electrostatic field collects around the PN junction which causes a breakdown of electrons, resulting in the Zener junction and the preset voltage of the device.

The 1EZ100D5E3/TR12 series of diodes have a voltage breakdown of 5V, a max temperature operating temperature of +85 deg Celsius and maximum power dissipation rating of 15W. This series is includes a wide variety of applications and is ideal for automotives, computer and industrial control, power supplies, EMC/ESD and multiple industrial applications. These features make the 1EZ100D5E3/TR12 series a great device for voltage regulation, so they can be trusted to handle various varied input voltage levels while maintaining the output at the required regulated level.
